I don't think there's a hurry to trade them and they aren't at a very good value level after last season. I'm down with seeing if they can have a good first half and sell at the deadline.
what would you be hoping to get even if they have good first halfs? I don't doubt that Holland has tried moving at least one of them in the past, and if they couldn't pull an established D at that point, I don't think that changes in the near future.
